Cellphone footage from a Global News reporter captured the tense moments as first responders struggled to save his life.

Dashcam video appeared to capture Parliament Hill shooter Michael Zehaf-Bibeau leaving the War Memorial immediately following the shooting.

Afterwards, witnesses to the shooting described the terrifying moments before, during, and after.

Then came the news which rocked the nation: at least one gunman fired multiple shots inside the halls of the Parliament buildings.

Footage shot by a Globe and Mail reporter captured the gun battle inside the seat of Canada’s federal government.

Another angle, this one shot by TVA, showed the frightening moment gunfire rang out down the halls of Parliament

After the battle and with police searching for at least one suspect, Scarborough MP John McKay described what he saw during the gun battle in this very candid interview.

Then came more shocking news: police officers some distance from Parliament blocked off an area near the Chateau Laurier while searching for the shooting suspect, drawing weapons while shouting for people to get back.

That was shortly followed by news directly from Ottawa police that they were searching for multiple suspects following the Parliament Hill attack.

Then came the news a short while later that yet another possible shooting incident was underway: Global’s Tom Clark describes the scene after he witnessed Ottawa police swarm the Rideau Centre.

A witness to the Rideau Centre shooting says the suspect managed to escape police.

Ottawa police later said that there was not a separate shooting incident at Rideau Centre. It is unclear why police stormed the centre or what the witness reported seeing.

A short while later, the RCMP and Ottawa Police held a press conference to confirm the details of the shooting at Parliament Hill earlier in the day.

Ottawa Police asked residents to remain vigilant but didn’t answer how many suspects may still be at-large.

At the end of the day, Prime Minister Stephen Harper addressed the nation, vowing that the people or organizations who perpetrated the attacks of the past week “would find no safe harbour”.

A lockdown that lasted into the evening ended at 8:25 p.m. ET, when the safety perimeter in downtown Ottawa was lifted. Police said there was no longer “a threat to public safety” in the downtown core, but police operations continued on Parliament Hill “and as such the Hill continues to be off limits to the public.”
